I am always interested in theory of knowledge and this memo has bunch of good thoughts
and some quotations are very apt. Here to mention a few.
The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
It talks about investment advice and issues around it, but I think it can easily be seen in any walk of life, be it career, relationships, health etc. we always want to know what future holds and hence there are industries around it, but knowledge needs to be understood before use, Another interesting Mark Twain quote it mentions and I have always used it frequently myself.
It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.
